But don’t write off Sidecar. The San Francisco company said Monday that it had raised $15 million to expand its footprint nationwide and to fuel its “Shared Rides” carpooling option. Virgin co-founder Richard Branson joined existing investors Avalon Ventures and Union Square Ventures.

The British billionaire made clear that he doesn’t think the book is closed on the ride company wars.

“An entrepreneurial company like Sidecar can take on the big guys with innovation and big ideas, not just big bank accounts,” he said in a Q&A with Sidecar. “It has been reported this is a winner takes all market, but it’s not. These are early days and, like a lot of other commodity businesses, there is room for innovators on great customer experiences.”

Branson, who also invested in taxi-hailing app Hailo, added: “Technology has turned transportation on its head. It’s fundamentally changing the way we get around. It has changed the taxi industry and allowed them to automate.”

The new funding brings Sidecar’s total raised to $35 million. Lyft has raied hundreds of millions; Uber, over a billion.
